1h all 'whom 'it mcg/concern.'

Be it known that I, RALPH V. SAGE, a citi-` z en of the United States, residingin the borcugh of Westmont, in the county of Camloria and State of Pennsylvania, have invented certain new and usefulV Improvements in-Car-Door Mechanism; and I do hereby declare the Vfollowing to be a full,

clear, and exact description of the invention,

such as will enable others skilled in 'the art to whichl it appertains to make andv use the same. y

My invention relates to operating and locking the drop doors of gondola or other cars, and the object of the invention is to provide quick and effective means for closing a series of car doors by employing a shaft, provided with worms, iiexible connections or chains winding thereon, and means for securing the individual doors when in their closed position :independently of each other and of the chains.

Briefly stated, the' invention yconsists in using a locking mechanism in connection with a worm-shaft and chain, or other flexil ble connection, such mechanism consisting of a bar pivoted-to the door and'adapted to' rest on the end of the worm when the doorA provided; Fig. 43 is a side elevation of one of the worms with a portion of the chain at-v tached thereto; Fig. l is an end view of the construction shown in Fig. 3; Fig. 5 1s also an end View of the same construction ytaken from thel opposite end of the device; and Fig. 6 is a view in section of the locking mechanism. Fig.7 is a separate perspective view of my pivoted locking-bar 7showing its supporting links and attachmentof the chain for closing the ldoorfand drawing the bolt into its locking-position.

Referring to-the drawings in detail, llrepresents the body of a car provided with longitudinal shafts 2 located at the sides innuediately beneath the floor and having worms 3 mounted thereon at points adjacent to the drop doors 4. U-shaped plates 5 (see F ig. 6) are secured to the under sides of these doors at the ends thereof and serve tov support the locking mechanism. This mechanism consists of two short links G pivoted to the lower portion of the-plate and extending upwardly, and -bars 7 to which the short links are pivoted in the manner shown in Figs. 2 and 6 of the drawings. The outer ends of the bars 7 project beyond the end of the door, and have openings through which a bolt 8 is passed, the latter having secured thereto a chain 9 connecting with the worm 3 on the horizontal shaft.' The bars 7 and their connecting bolt will be termed the locking-bar. The worm is provided at one end with ears l() through which pass bolts ll for securing the chain. These ears have several openings, as shown in a and 5, in order to provide for adjustment. At the opposite end of the worm the flange is slightly deflected and formed into a lug l2 for engaging the end of the bars 7.

T he operation of my apparatus in closing the car door is as follows: Referring to Fig. 2 .of the drawings, in which the dropdoors are shown in their lowered positions, `the shaft. 2 is rotated in a proper direction by the use of awrench applied to the ratchet mechanism 13, or other suitable means, causing the iexible connection or chain 9 to be wound upon the worm 3. I/Vhen this has proceeded suiiiciently to allow the extreme end of the locking-bar to come close to or in contact with the surface of the wormv 3, thewinding of the shaft is continued in the same direction, whereby the end ofthe locking-bar moves upward and around the worm and finally is progected over and rests upon thenpper surface of the said worm, thusv serving as a positive support and lock for the doors. I may substitutea. cylindrical sleeve for the worm or may omit it altogether, using. the surface of the windingshaft.V itself as a bearing for the locking-bar. However, I prefer to use a worm, as under certain conditions it distributes the chain more evenly and prevents kinks in the same.

The use of some such secondary member to forni the bearing surface is economical in thatit ise'asily renewed and, owing to its larger circumference, does not spread the Wound-up chain over as great av distance as vvould the Winding-shaftI itself, so that the bolt/'s subjected to less pull in a sidewise di` rection, In unlocking the door, the rotation of the sliaft and the vvorm thereon in the reverse direction causes the lug to'come in Contact with the end of the locking-bar throwing it. ii'i'vvardly, releasiiigit from its bearing on the'vvorm and allowing the door to drop into the position shovvn in dotted lines in Fig. 2. It will be observed that when the doors are in their closed position ach door is held by its individual lock, the

`} )rinci.-pal function of the chain being tol vclose the unlocked door. The shaft is Well out of the Way of the cargo and the advantages resulting` from a Wide door-opening are secured.

All'hile I have shown and described my invention in considerable detail, I do not vvisli to he limited to the exact construction specilied, but may use such substitutions, modi cations or alterations as fall vvithin the scope of the invention set forth in the claims.

ll'hat I claim as nenv and desire to secure by Letters Patent is:
